CARD-BOARD-BOX FASTENING.

SPECIFICATION forming part of Letters Patent No. 367,970, dated August 9, 1887.

Application filed December 30, 1886. Serial lN'n. 222,986. (No model.)

To all whom it may concern.-

Be it known that l, .Taoon Gamma, manir factnrcr of cardboard boxes in StnttgartflViirtcinberg, Germany, have invented certain new and useful lmproi 'ementsin Machines for Mak ing Metal l astening lips for Card-Board and like Boxes, of which the following is aspecifi- 1 cation.

"ing the corner of the box, of pressing-plates for bending over the ends of the prongs of the clips.

The invention also consists in the construction and combination of parts and details, as will be fully described and set forth hereinafter and finally pointed out in the claims.

In the accompanying drawings, Figure 1 is a side view of my improved machine forshap ing, sheet-metal angle-c|ips, parts being in section. Fig. 2 is apla-n view of the'samc. Fig. l is a face view ofone of the blanks for making the clips. Fig. -l is a sectional plan view of the same. l ig. 5 is a sectional plan view of the clip bent. Fig. ii is a sectional plan view of the clip having the prongs bent.

' Similar letters of reference indicate corre- Spending parts.

The female die 11!, which is provided with a V-shapcd groove, into which pattof the blank 0 is pressed, is mounted to slide transversely in a slot in the frame or body A of the machine, said female die in being connected pivotally at l with one end of a lever, It, pivoted at i. A cam, in, on a shaft, \V, acts on that end of the lover It opposite the one connected with the female die an.

The male die 1", which fits into the groove jections serve for registering the blank 0..

of the female die ill, is secured on a slide,f, which is operated by a cam, 11, on the shaft \V. Two levers, c,'arc pivoted at ef in the frame A, each lever having one end adjacent to the side of the male die 1) and the other end resting againstthe cam projections :10, of which there is one on each' side of the cam d. A spring, K, is fastened to the lever hand to the fixed part of the frame, and draws the female die at into the position shown in full lines in .Fig. 1. On that part of the frame in which the female die in slides projections are provided at the sides of said sliding female die, which pro- When the female die is in the position shown in full lines, the blank 0, having the side.

prongs, .2, is placed over the V-shaped groove in the female die, and, with the said die at, enters the slotin the frame A, and thenthe cam 11, acting on the slide f, presses the male die p against the clip, whereby the same is pressed into the shape shown in Fig. 5-that is, V- sliapcd. The projections :r then act on the levers 1:, whereby the front ends of the lovers 6 press the prongs of the blank 0 into the position shown in Fig. (i. The lever h is then moved into the position shown in full lines in Fig. 1 and the clip drops out of the machine. The spring f serves to draw the lovers e to ward each other.

.1 [mi ng thus described my inventionl claim as new and desire to secure by Letters Patent- The combination, with a frame, A, of a sliding die, 1), and a die, in, mounted to slide in a slot in the frame at the lower end of a sliding die, which slot is at right angles to the direction in which the die p slides, so that the said die at will slide at right angles to the dicp, substantially as shown and described.

2. The (mmbination, with the frame A, of the female die n1,havi ng a Vshaped grooveand monnted to slide transversely in the frame, the die mounted to slide longitudinally in the frame, and the levers 1*, having their ends adjacent to the die 1), substantially as shown and described.

:3. The combination, with the frame A, of

the die m, mounted to slide transversely in the some, the pivot ed lever 71, connected with the In testimony that; I claim bheioi'egoing as my die in, the shaft \V, the cum w on the same, invention I have signed my name in presence the slide f, the emu d, :ieling on the same, of two subscribing witnesses.
